Energy of different energy shell

Postby George_Zhu » Thu Jul 04, 2019 1:09 pm

Is the energy in low energy shell lower or higher than the energy in high energy shell?

The lower the principal quantum number (n) the lower the energy of the electron. This means that lower energy shells contain electrons with less energy. When an electron becomes excited and "jumps" to the next energy level (i.e. n=1 to n=2), the electron has gained energy. When the electron returns to the original energy level it "loses" energy by emitting electromagnetic (EM) radiation.
